Charl Schwartzel has withdrawn from the South African Open after picking up a stomach virus.
The former Masters champion had been in hospital intermittently for treatment and had to go for rehydration treatment.
The South African Open, which takes place at Johannesburg's Glendower Golf Club from January 7 to 10 is one of the few titles Schwartzel is yet to win in his homeland.
"I am hugely disappointed to be missing out on the SA Open," Schwartzel said in a statement to the media.
"Everybody knows how keen I am to win our national Open and, having come so close the last couple of years and following my good form at Leopard Creek, I was really looking forward to contending at Glendower.
"I look forward to being strong and healthy in time for the Joburg Open the following week."
